Acoustica Products




All modern buildings contain services to provide heat, water, light, power and ventilation, noise and vibration are an issue that many of these services require attention from qualified and experienced engineers to resolve. Over many years we have developed a range of standard solutions that we can deploy in solving these challenges. The utilisation of internally developed software and certified test data enables us recommend a solution with such confidence that we are able to GUARANTEE the resultant acoustic levels within the design space. Uniquely over many thousands of installations we have never had a noise level problem.

Our design team will be happy to give you advice and guidance on the best selection and orientation of proposed equipment and recommend acoustic solutions that minimise the energy loss or system resistances, and space requirements.

We have a range of 12 product groups that we deploy in the AERO ACOUSTICS sphere including the renowned LIMPET range of innovations. Our renowned Limpet range of innovations are designed to improve the performance of several fan related noise and vibration control products. The design emphasis has included the requirement for all limpet products to be easier to install and more reliable in operation.









We are seeking to launch another eight innovative products over the next two years roughly at one per quarter many aimed at the building services sector with a view to improving performance and ease installation of noise control products. As one building services contractor recently said “I can’t wait to see what you guys come up with next”




Aero- Acoustics Technical Guides



A noise level specified as a dB(A) level is a weighted logarithmic average of a set of frequency specific sound levels.

The weighting system is designed to adjust the sound levels to an approximation of the human ear response. The addition of the individual weighted values is designed to combine the sound spectrum into one single figure for comparitive purposes. Click Thumb to download 













Noise Rating Levels or NR Level Curves are developed by the International Organization for Standardization (ISO) and specify an  indoor acoustic environment for different requirements of hearing preservation, speech communication and annoyance, in different applications.
Noise Rating values for different sound pressure levels are tabulated below and are the established sound pressure levels at different frequencies. Noise Ratings are then used to specify the maximum permissable sound power level at each frequency by selecting a single Noise Rating (NR) number. The use of Noise Rating - NR - is widespread across Europe. 
Noise Criterion or NC levels are a different set of values developed for the same purpose, the use of Noise Criterion (NC) is mainly used in North America. Click Thumb to download
